After helping to inaugurate CNN.com on the Internet in the early 1990s, Garzik worked at a succession of Internet startups and service providers for over two decades, all while working on open source software engineering projects. Involvement in one of the best-known open source projects, the Linux kernel, led to an extended tenure at Linux leader Red Hat, during open source's most formative years.
